I recently purchased Evohome for all the radiators in my house plus a hot water control.

However, while I thought I might be able to self install the wiring was too much for me and all my radiators require new valves fitted.

I have arranged an electrican to do all the electrical work and separately going to get a plumber to replace the valves.

The electrican will be here a couple of weeks before the plumber (Christmas schedules!)

Wondering if I can bind a HR92 that isnt connected to a radiator and use that to control the boiler if it is bound through the control.

I accept I will have no control over heating in other rooms apart from existing TRVs just wondering if it is possible to do?
